For real if I wanted RGB footwell lighting I would install it myself. And I did, in my first beater car, as a dumb teenager does. I thought it looked pretty cool.
But now as a grown man I want a car to start every time, go fast when I step on the pedal, and have AC like a refrigerator. If it's a truck I want it to pull heavy trailers and not get stuck in mud and THAT'S IT.
Currently driving a 2008 Crown Vic and a 1978 F350 on propane, both of which do exactly what I want.
